Abstract:The traditional water abundance assessment methods cannot effectively reflect water abundance zoning due to the uncertain problem of influence factors and the problem of less hydrogeological test boreholes.Therefore,the evaluation index system composed of mass ratio of sand and clay,total thickness of gravel layers,amount of gravel layers and aquifer thickness was established employing the law of sedimentary characteristics controlling groundwater.Comprehensive weighting-unascertained measure theory coupled evaluation model was used to evaluate water abundance of loose aquifer at the bottom of Quaternary,which could determine the types of safety coal and rock pillar under water body.Finally,a case study in Danhou mine of Yuxian mining area was carried out.The results show that the method effectively solving water abundance zoning of loose aquifer provides a new idea for water abundance evaluation of loose aquifer in water-preserved mining regionalization.
